Disc Flushing Valve – Fig 938

The Disc Flushing Valve has a circular aperture suitable for wall or flange mounting.  A wall hook secures the valve in the open and intermediate positions via the lifting handle. The disc flushing valve is supplied with an impact device for easy opening.

The handle mass may be a determining factor for the duty.  Maximum handle lengths of 4 metres are recommended for comfortable equipment operation. Lengths over 4 metres can be supplied on request.

The disc is designed to withstand a standard on-seating head of 10 metres but, dependent on size, will take a degree of off-seating pressure.
